Patent FI-76846-C (FI)
Inventor: LAAKSO OLIVER ARMAS
IPC: D21C7/00
Filed: 1984-05-07
Granted: 1988-12-12
Abstract: Comminuted cellulosic fibrous material, such as wood chips, are treated in a continuous digester to produce paper pulp or the like in a manner providing completely uniform treatment of the chips. The chips are introduced in a feed liquid slurry into the top of the digester, with a swirling action, and establish a vertical column in the digester having a substantially horizontal top, with some liquid between the top of the digester and the top of the chips. Below the top of the chips the feed liquor is withdrawn through a first set of withdrawal screens, and recirculated to entrain other chips to feed them to the top of the vessel. At other vertically spaced areas of the digester other screens are provided for withdrawing, cooking, quench, washing, and like liquors, and effecting recirculation thereof. At each screen set a plurality of nozzles are provided circumferentially spaced around the digester, each nozzle cooperating with only a particular radial segment of the screens. Withdrawal of liquid through the nozzles is practiced so that liquid is being withdrawn substantially through only one nozzle at a time, and it is being withdrawn at the same radial segment of the digester at each screen set at any particular point in time, with progressive switching in a circumferential sequence of the nozzles through which liquor is being withdrawn. Thus deliberate channeling of treatment liquors through the chips column is provided.

Abstract: A method for joining insulated conduits is disclosed, in which the bared ends of the medium-carrying pipes are first interconnected in a per se known manner and a union piece is thereafter placed around the resulting joint, such that the union piece has an overlap on the outer side of the conduits to be joined and forms a mould for foaming an insulating material of cellular plastic in the joint. The union piece is a relatively rigid, circumferentially resilient plastic tube which is slotted throughout its entire length and, before being applied around the joint, has an inner diameter which is smaller than the outer diameter of the conduits. After the union piece has been applied around the joint, a strip is placed on the slot of the union piece throughout substantially the entire length of the slot, said strip consisting of a mouldable, curable plastic material which by curing is bondable to the union piece, and which is thereafter cured so as to be bonded to the union piece.

Patent NL-90384-C (NL)
IPC: B02C15/12
Abstract: Isopropyl nitrate is prepared by the continuous distillation of a mixture of easily volatile products from a liquid reaction mixture which is at a temperature not below the boiling point of the azeotropic mixture of isopropyl nitrate and water and is formed from nitric acid and isopropyl alcohol and into which separate streams of nitric acid and isopropyl alcohol are introduced and in which a urea concentration sufficient to destroy nitrous acid is maintained, at least the isopropyl alcohol being introduced as a vapour below the surface of the liquid reaction mixture.  At atmospheric pressure the reaction mixture should be at a temperature of not less than 80.5 DEG C. and preferably above 100 DEG  C.  The isopropyl alcohol vapour is preferably slightly superheated and preferably consists of an azeotropic mixture of isopropyl alcohol with water, such as that produced by boiling aqueous isopropyl alcohol of higher water content than the azeotropic mixture.  The nitric acid concentration of the reaction mixture, including that combined with urea, is preferably from 35-60 per cent by weight, and that of urea is preferably maintained from start to finish at not less than 3 per cent by weight.  The desired ammonium nitrate concentration in the reaction mixture is maintained by running a proportion of reaction mixture continuously to waste. Specifications 379,312, 540,050 and 696,489 are referred to.

Title: Separation method
Inventor: BRIDGER NEVILL JOHN
IPC: B01J47/08
Filed: 1991-01-29
Granted: 2000-05-02
Abstract: A first metal, for example a transition metal such as cobalt, having an insoluble hydroxide is separated from a second metal such as lithium having a soluble hydroxide in an aqueous liquid containing dissolved rations of the metals. The cations are firstly absorbed onto a cation exchange material by electrochemical ion exchange and the second metal then selectively eluted by electrochemical ion exchange under sufficiently high pH conditions, e.g. to 10-13, in a closed loop. Finally, the transition metal is eluted by electrochemical ion exchange under sufficiently low pH conditions, e.g. acidic such as 1-2. The method is applicable to separating trace quantities of Co (e.g, as Co-60) from larger quantities of Li in aqueous solution.

Title: Extended kraft cooking with white liquor added to wash circulation
Inventor: STROMBERG BERTIL
IPC: D21C7/14
Filed: 1991-03-07
Granted: 1996-03-05
Abstract: In the continuous kraft pulping of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, viscosity for a given Kappa Number is significantly increased (e.g. at least about 20%) by adding kraft white liquor to the wash recirculation loop in a continuous digester.  Optimum results are obtained when kraft white liquor is also added to a recirculation loop at a central portion of the digester, so that the majority of the digester has countercurrent flow between white liquor and cellulosic material.  About 5-20% of the total white liquor  necessary to effect kraft cooking is introduced in the wash circulation, and about 10-20% is introduced into the central portion recirculation.  The temperature in the wash zone is maintained at about 140-175°C.
